Charged: Battery Bug

Few things are as annoying as stepping aboard your boat and finding that its batteries are dead. The Battery Bug from Argus Analyzers shows how much juice is left in a deep-cycle or dual-purpose battery and how much capacity has been lost; it has a replace-battery indicator and a low-battery alarm. It compensates for ambient temperature and is self-calibrating. Argus Analyzers claims that install time is less than two minutes. Battery Bugs are available for batteries of different sizes and voltages.

$39.95. Argus Analyzers, 401-398-2959,
